yum安装软件时，提示No package netstat available.的解决方法

1. 序言

如笔者在本机上运行netstat时，提示没有这个命令，向来简单粗暴，直接yum -y install netstat，显然是不能正常安装的。

[root@hadoop-103 ~]# yum -y install netstat

[root@hadoop-103 ~]# 

这种情况下，怎么办呢？

2. 使用“yum search”命令

此时可以使用“yum search”来查询这个命令在哪个包中：

[root@hadoop-103 ~]$ yum search netstat
Loaded plugins: fastestmirror
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast

dstat.noarch : Versatile resource statistics tool
net-snmp.x86_64 : A collection of SNMP protocol tools and libraries
net-tools.x86_64 : Basic networking tools    #这里已经给出了netstat命令所在包

接着直接安装这个包即可：yum -y install net-tools

3.使用“yum whatprovides ”查询命令所在的包

还可以使用yum whatprovides

[root@hadoop-103 ~]# yum  whatprovides *netstat
